Figure 4

Shear rheology experiments on compression-molded PCL-PX samples. (a) Stress relaxation experiments under 1% strain with temperature variation. Relaxation plots fitted with stretched exponential decay (eq 1) (yellow dashed lines). (b) Arrhenius plot using characteristic relaxation times (τ) obtained from fit in plot a. (c) Frequency sweep experiments at different temperatures. (d) Creep-recovery experiments at room temperature (magnified in the inset), 60 °C (∼15 °C above melting temperature) and 100 °C (processing temperature).
